12 . The UE of claim 7 , wherein in response to the DCI format scheduling a physical uplink shared channel (PUSCH) for carrying the TB on the super slot,
a timing offset between a physical downlink control channel (PDCCH) carrying the DCI format and the PUSCH is indicated by the DCI format in units of super slot.
13 . The UE of claim 7 , wherein in response to the DCI format scheduling the TB on the super slot,
the entry of the TDRA list includes at least one start and length indicator value (SLIV) indicating an index of a first scheduled symbol in a first slot of the super slot and a number of scheduled symbols in a last slot of the super slot; or
the entry of the TDRA list indicates at least the index of the first scheduled symbol in the first slot of the super slot and an index of a last scheduled symbol in the last slot of the super slot.
14 . The UE of claim 7 , wherein in response to the DCI format scheduling the TB on the super slot, the DCI format indicates at least one of:
a start and length indicator value (SLIV) indicating an index of a first scheduled symbol in a first slot of the super slot and a number of scheduled symbols in a last slot of the super slot;
the index of the first scheduled symbol in the first slot of the super slot and an index of a last scheduled symbol in the last slot of the super slot;
the index of the first scheduled symbol in the first slot of the super slot;
the index of the last scheduled symbol in the last slot of the super slot; and
a super slot level offset between a super slot where the DCI format is received and a super slot where the TB is scheduled.
